Ocean/Marine Research, Education, and Outreach
Rafe Sagarin, rafe@email.arizona.edu, Biosphere 2 and Institute of the Environment
Dr. Sagarin and colleagues are transforming the Ocean Viewing Gallery to house an exciting new display about
exploring the Gulf of California. New marine research, lesson plans, and other opportunities are being planned
to accompany the future transition of the coral reef ecosystem to an analog of our Desert Sea – the nearby
Mexican ocean that exchanges nutrients, energy, and much more with our Sonoran Desert region. Join Dr.
Sagarin and snorkel in the B2 Ocean, learn marine science, help determine which species to introduce to the
changing ecosystem, research the mangrove swamp, and more.
Education and Outreach, Translating Research Findings for the Public
Kevin Bonine, kebonine@email.arizona.edu, Biosphere 2, College of Science, Ecology & Evolutionary Biology
Dr. Bonine is a herpetologist, ecologist, evolutionary biologist, and conservation biologist. He is also the
Director of Education and Outreach at Biosphere 2. Myriad opportunities are available with him to study how
best to engage visitors and school groups at Biosphere 2, how best to teach complex ecosystem principles, and
how to ensure that researchers present their findings in a way that the public can understand. Talking with
visitors, generating surveys, planning nature trails or educational playgrounds, refining age-appropriate
lessons, teaching school kids, and deploying wildlife cameras can all be part of your internship experience.
Program evaluation
Kevin Bonine kebonie@email.arizona.edu or Joost van Haren, jvanhare@email.arizona.edu
In science and outreach not enough time is taken to evaluate in how far the programs, strategies, or exhibits are
actually accomplishing what they were designed for. Evaluation requires a clear communication of the leader
to state the objectives and goals of a program, then an evaluator can design a methodology to test which
objectives and goals are reached. Students can work with Kevin Bonine or Joost van Haren to develop and
implement program evaluation of projects potentially related, but not limited, to the visitor programs, exhibits,
tours, research projects, and needs assessment. The students would work with Allison Titcomb (a University
evaluation expert) to determine the relevant methodologies and assessment strategy.
Urban Ecosystems
Mitch Pavao-Zuckerman, mzucker@email.arizona.edu, Biosphere 2
Dr. Pavao-Zuckerman studies the contribution of organisms to biogeochemical cycling, one key point in linking
across scales in ecosystems. The response of organisms to their local environment reflects one way in which
ecosystems directly respond to land-use change, and climate. His lab group focuses on the connections between
the structure of soil food webs and biogeochemical cycling in human-dominated landscapes and urbanized
ecosystems. The B2 campus serves as a model city ecosystem for such studies using meso-scale experiments
related to green infrastructure. He has focused on microbial and microfaunal diversity, carbon fluxes, and
nutrient transformations at B2 and in wild and urbanized environments in southwestern Arizona. Research
projects for interns could focus on microcosm studies and observational studies in B2 experiments and real
world settings to investigate the interactions between the biological structure of ecosystems and nutrient
cycling.
Soil Chemistry and Soil Formation
Katerina Dontsova, dontsova@email.arizona.edu, Biosphere 2
With Dr. Dontsova, students will have the opportunity to participate in one of several ongoing projects at B2
that focus on soil formation processes. The projects range in scale from Landscape Evolution Observatory (
LEO) (340 m2 area, 1 m soil depth) to large mesocosms with mesquite and grasses ( 0.26 m2 area, 1 m depth) to
smaller and more controlled systems (20 cm2 area, 30 cm depth). Students can observe the changes that are
happening in the rock during initial stages of soil formation as a result of water flow and biological activity. In
the small mesocosms students will be working on establishing the role of root-mycorrhizae-bacterial
associations on the extent of total weathering and chemical denudation. Specifically, to what extent does the
biota (plants and microbes) contribute to weathering rock to form high surface area secondary solids while also
diminishing the loss of weathering products in solution. Interns may use direct measurements and geochemical
modeling. Dr. Dontsova and her colleagues have hypothesized that plant and microbial/fungal effects are
synergistic and not simply additive. In larger mesocosms research can link measured weathering, denudation,
and carbon sequestration in the soil to water transpiration, plant photosynthesis, and plant and soil
respiration; while LEO research can focus on development of subsurface heterogeneity through hydrologicgeochemical coupling.
Ecology and Carbon & Water Cycling
Dr. Greg Barron-Gafford, gregbg@email.arizona.edu, Biosphere 2 and School of Geography
Dr. Barron-Gafford studies ecohydrology in mountain and valley ecosystems in the desert southwest. His
interdisciplinary research involves measuring leaf and soil carbon and water fluxes with the goal of better
understanding how semiarid environments will respond to climatic stresses of temperature, summer drought,
and reduced mountain snow input. He and his colleagues can estimate the component fluxes within subcanopy and canopy species in the Santa Catalina Mountains and in the Santa Rita Experimental Range that
border Tucson to the north and south, respectively. Potential projects include measuring carbon and water
exchange with the atmosphere in individual trees or whole sub-canopy plots to capture variation due to canopy
cover (a biological influence), slope and/or aspect (a physical driver), and changing climate (atmospheric
influences). Methods may include measures of plant water status, hemispherical photography (to quantify
incoming solar radiation), and leaf/plot/soil gas exchange with the atmosphere. His group is interested in how
these ecosystems will perform under projected climate change scenarios, which species might begin
dominating the ecosystem, and how tightly coupled carbon uptake is to water availability in this semiarid, sky
island setting. The internship experience can include fieldwork or center on lab activities depending on student
interest and availability. More information on Barron-Gafford’s research and lab members can be found at
http://www.u.arizona.edu/~gregbg/Home.html
Water Movement Across the Landscape
Peter Troch and Luke Pangle, lpangle@email.arizona.edu, Biosphere 2 and Hydrology & Water Resources
Drs. Troch and Pangle want to better understand catchment scale hydrological processes, including water
transit time, through advanced measurement, modeling and synthesis methods. The objectives of their
research include: (1) Developing, testing and applying advanced observation methods for hydrological fluxes
and states at a range of spatial and temporal scales; (2) Developing hillslope to catchment scale hydrological
models for water and solute transport; and (3) Hydrological synthesis at the catchment scale with special
attention to hydrological extremes. The motivation of their work is to contribute to improved water resources
management in the light of climate change and other human influences on the hydrological cycle. Students
working in their lab may work on water transit time estimation using stable isotope data from rain and
streamflow samples. The internship experience can include field work, lab work that includes running the laser
spectrophotometer, and mathematical modeling of flow and transport processes at catchment scales.
Plant Growth, Physiology, and Phenology
David Moore, davidjpmoore@email.arizona.edu, School of Natural Resources and the Environment
Plants take up about half of all the carbon produced by humanity through the process of photosynthesis but
there are many unanswered questions about how long this will continue especially as spring arrives earlier and
autumn later, for some plant populations. Dr. Moore’s lab group aims to discover the environmental triggers
for major phenological events in cottonwood trees by studying patterns of leaf development, plant
photosynthesis, and growth. Interns will work at B2 using an experimental stand of trees. Depending on their
interests students can learn how to carry out physiological measurements, image analysis, spectral
measurements of leaves, and other laboratory techniques.
Computer modeling of terrestrial hydrology, ecology, and climate change
Guo-Yue Niu, niug@email.arizona.edu, Biosphere 2 and Hydrology & Water Resources
To enhance our understanding of the interactions between the soil, plants, and air and their integrated
behavior at hillslope and catchment scales, Dr. Niu’s group is developing a Terrestrial Integrated Modeling
System (TIMS) for modeling hydrological, microbial, geochemical, geomorphological, and ecological processes
at the Earth’s land surface. The coupled model will be used for interpreting LEO measurements and three other
projects funded by federal agencies: 1) an NSF-funded biology project for exploring the impacts of climate
change and rainfall redistribution over complex terrain on the spread of invasive species, 2) a DOE-funded
Earth System Model (ESM) project to develop a global high spatial resolution land surface modeling system for
studying the interactions between climate and the global water cycle, and 3) an NSF-funded project to study
the integrated processes of energy, water and carbon in the Jemez-Catalina Critical Zone.
Rainforest Response to Climate Change and trace gas exchange across the soil-atmosphere
boundary
Joost van Haren, jvanhare@email.arizona.edu, Biosphere 2 and Honors College Dr. van Haren studies the
effect of climate change on tropical ecosystem activity and in particular the exchange of greenhouse gases
across the soil-atmosphere boundary. Tropical forests are the most dynamic ecosystems in the world, however
they are threatened by deforestation and climate change. The potential response of tropical forests to climate
change is uncertain, because little experimentation under predicted future environmental conditions
(increased temperature and decreased precipitation) has been done in tropical ecosystems. Biosphere 2
provides an opportunity to study tropical ecosystem processes under future conditions. The student(s) involved
in this project will have the opportunity to work within the B2 tropical forest to investigate both plant and
microbial responses to changing temperature and precipitation. The exchange of greenhouse gases across the
soil-atmosphere boundary greatly influences the global budgets of these gases, but is still poorly understood,
especially in regard to the influence of biology on the rates. In Biosphere 2, students will have the opportunity
to measure the gas exchange in a range of ecosystems from pure bare soil (LEO) to tropical vegetation.
